The Kaplan-Meier survival curve estimates the probability of survival over time for different patient groups. Here, we compare survival probabilities based on MHC-II status. The risk table shows the number of patients remaining at risk at different time points. The p-value from the log-rank test suggests there is no statistically significant difference between groups.
The Cox proportional hazards model estimates the effect of various clinical and biological factors on survival risk. Each hazard ratio (HR) represents the relative risk of death associated with a given variable. Values greater than 1 indicate an increased risk, while values less than 1 suggest a protective effect. Confidence intervals help assess the reliability of each estimate.
